termination, receiving data, timeout) used in SOCKET n. When an interrupt occurs and the
mask bit of Sn_IMR is ‘1’, the interrupt bit of Sn_IR becomes ‘1’.
Sn_IR is cleared (‘0’), IR(n) is automatically cleared. It occurs the INT5 signal (nINT5:
TCPIPCore interrupt) to MCU.
Below commands are only valid for SOCKET 0 and S0_MR(P3:P0) = S0_MR_PPPoE.
For more detail refer to the W5100 application note “How to use ADSL”.
Sn_IR (SOCKET n Interrupt Register)[R/W][0xFE4002 + 0x100n][0x00]
Sn_IR register provides information such as the type of interrupt (establishment,

PPP Fail Interrupt, when PAP Authentication is failed
PPP Next Phase Interrupt, when the phase is changed during ADSL
connection process
SEND OK Interrupt, when the SEND command is completed
It checks the connection status by sending the keep alive packet. If the
connection has no response from peers or is terminated, the Timeout
interrupt will occur.
RECV processes the data received by using a RX read pointer
register(Sn_RX_RD).

Write Pointer Register(Sn_RX_WR), and SOCKET n RX Read Pointer
Register(Sn_RX_RD).
